+## Design
+**MindMyMoney** is written fully in **Java 11** using Object-Oriented Programming (OOP) paradigm to help structure and
+organise the code. This enables the efficiency of future improvements and revisions.
+Data stored in the application is saved into text files locally on the user's device.
-* *glossary item* - Definition
+
+
+### Architecture Overview
+
+Fig 1 - Architecture Diagram for MindMyMoney
+
+The Architecture Diagram above shows the high-level design of the application. The **main components**
+consist of:
+- `MMM`: Initialises the components in the correct sequence and connects them with each other. Also holds the user's
+expenditures in memory.
+- `Ui`: The User Interface of the application and deals with interaction with the user.
+- `Parser`: Deals with making sense of user commands.
+- `Commands`: The collection of all executable commands.
+- `Storage`: Reads data from, and writes data to the hard disk.
+
+By abstracting out closely related code into classes, it allows `MMM` to deal at a higher level, without worrying
+about the lower level details. Higher cohesion is also achieved and coupling is minimized.
+
+
+
+The Sequence Diagram below shows an example of how the components interact with each other for the scenario
+where the user issues the command `add /e /pm cash /c food /d Porridge /a 3 /t 04/04/2022` to add an expenditure.
+
+
+
Fig 2 - Sequence Diagram showing the Add Command
+
+
+
+### Component Overview
+The major code is broken down into components for better abstraction.
+The sections below give more details for each component.
+
+
+
+### UI component
+The source code can be found in [`Ui.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/Ui.java)
+
+
+
Fig 3 - Ui Class Diagram
+
+The UI component consists of a `Ui` and `PrintStrings` class.
+
+The UI component:
+- Prints the welcome banner and message on startup, as well as a financial tip from the `PrintStrings` class.
+- Prints `>` before the user's input, to help the user differentiate between their input and an output from the
+application.
+- Reads input from the user.
+
+
+
+### Parser component
+The source code can be found in [`Parser.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/Parser.java)
+
+
+
Fig 4 - Parser Class Diagram
+
+The Parser component consists of a `Parser` and `User` class. The `User` class further consists of an `ExpenditureList`,
+`CreditCardList` and `IncomeList` class, which makes use of the `Expenditure`, `CreditCard` and `Income` class respectively.
+
+The Parser component:
+- Receives user's input and splits it into the Command Type and Description using the `GeneralFunctions` class.
+- Uses the `User` class and user's input to instantiate a `Command` object based on the Command Type.
+- Returns the `Command` object that can then be executed.
+
+We pass in the `User` class to the `Command` object instead of using a global variable to ease testing. This way, we can
+add, delete and update entries in a new `User` during testing without affecting the actual `User`.
+
+
+
+### Command component
+The source can be found in [`command`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/command)
+
+
+Fig 5 - Command Class Diagram
+
+The Command component consists of Command abstract class, `AddCommand`, `ByeCommand`, `DeleteCommand`, `HelpCommand`
+,`CalculateInputCommand`, `ListCommand`and `UpdateCommand` that extends the `Command` class.
+
+The Command component:
+- Provides all the Command classes which can be instantiated by `Parser.parseCommand()`. The Command objects can then be
+executed. Only 1 Command object can be created.
+- Includes a `Command.executeCommand()` method in each Command classes which performs the relevant command and throws
+exceptions if an error is encountered. The error is then handled.
+
+
+
+### Storage component
+The source can be found in [`Storage.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/Storage.java)
+
+
+Fig 6 - Storage Class Diagram
+
+The Storage component consists of `Storage` class.
+
+The Storage component:
+- `MMM` class initialises a `Storage` object upon start up. The `Storage` class consists of
+`Storage.load()` and `Storage.save()` methods.
+- Concurrently, `MMM` will call the `Storage.load()` method and load any data that is stored on the hard disk.
+- `MMM` calls the `Storage.save()` method and stores remaining data onto the hard disk when the program exits.
+
+
+
+## Implementation
+This section describes some noteworthy details on how certain features of MindMyMoney are implemented.
+
+
+
+### Add Command
+The source code can be found in [`AddCommand.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/command/AddCommand.java)
+
+The Add Command feature allows users to add expenditures, credit cards or their income using a single command.
+This provides speed and ease of use by only requiring a single line of input.
+
+The Add Command has 3 parts. These parts are differentiated by their flags:
+- Add expenditure `/e`.
+- Add credit card `/cc`.
+- Add income `/i`.
+
+The sequence diagram below shows the interactions when an `AddCommand` is executed.
+
+
+Fig 7 - AddCommand Sequence Diagram
+
+Below is an example showing how the AddCommand behaves at each step.
+1. The `Parser` component parses user input and returns the new `AddCommand` object to the
+ `MindMyMoney`.
+2. `AddCommand` instantiates `addInput`, `expenditureList`, `creditCardList`, `incomeList`.
+3. The application invokes `AddCommand.executeCommand()` to execute user instruction.
+4. If user input contains `/e`, the application executes `AddCommand.addExpenditure()`.
+5. Else user input contains `/cc`, the application executes `AddCommand.addCreditCard()`.
+6. Else if user input contains `/i`, the application executes `AddCommand.addIncome()`.
+7. The application then returns to the Parser component.
+
+
+
+#### Add Expenditure `/e`
+A key functionality of MindMyMoney is the ability to add and track user expenditure. Expenditures are added through
+the `AddCommand.addExpenditure()` method, invoked when using the `/e` flag. Additional parameters `PAYMENT_METHOD`,
+`CATEGORY`, `DESCRIPTION`, `AMOUNT` and `TIME` are also required.
+
+
+
+Fig 8 - Add Expenditure Command Sequence Diagram
+
+The sequence diagram above shows the interactions of different classes when adding an expenditure
+to the list.
+
+1. During the execution, `AddCommand.addExpenditure()` will parse through user input to obtain the `PAYMENT_METHOD`, `CATEGORY`,
+ `DESCRIPTION`, `AMOUNT` and `TIME` fields.
+2. Once all the fields are obtained, `AddCommand.addExpenditure()` will run tests for its respective fields.
+3. The `AddCommand.addExpenditure()` object formats the `CATEGORY` and `AMOUNT` fields, and the `PAYMENT_METHOD` if it is cash.
+4. The `AddCommand.addExpenditure()` object instantiates a new `Expenditure` object with the 5 fields and adds them
+ into the `ExpenditureList`.
+5. The `AddCommand.addExpenditure()` object prints a list to show the user what it has saved.
+6. If user input for `PAYMENT_METHOD` is not cash, `AddCommand.addExpenditure()` invokes `AddCommand.updateCreditCardTotalExpenditure` to update the corresponding `creditCard.totalExpenditure`
+7. The `AddCommand.addExpenditure()` returns to `AddCommand`.
+
+
+
+#### Add Credit Card `/cc`
+MindMyMoney allows users to track their different credit cards. Credit cards are added through the `AddCommand.addCreditCard()`
+method, invoked when using the `/cc` flag. Additional parameters `CREDIT_CARD_NAME`, `CASHBACK` and `CARD_LIMIT` are also
+required.
+
+
+Fig 9 - Add Credit Card Command Sequence Diagram
+
+The sequence diagram above shows the interactions of different classes when adding a credit card to the list.
+
+1. During the execution, `AddCommand.addCreditCard()` will parse through user input to obtain the `CREDIT_CARD_NAME`, `CATEGORY`,
+ `CASH_BACK` and `CARD_LIMIT` fields.
+2. Once all the fields are obtained, `AddCommand.addExpenditure()` will run tests for its respective fields.
+3. The `AddCommand.addCreditCard()` object instantiates a new `CreditCard`
+ object with the aforementioned 3 fields and adds them into the `CreditCardList`.
+4. The `AddCommand.addCreditCard()` object prints a list to show the user what it has saved.
+5. The `AddCommand.addCreditCard()` returns to `AddCommand`.
+
+
+
+#### Add Income `/i`
+MindMyMoney allows users to track their sources of income. Incomes are added through the `AddCommand.addIncome()`
+method, invoked when using the `/i` flag. Additional parameters `AMOUNT` and `CATEGORY` are also required.
+
+
+
Fig 10 - Add Income Sequence Diagram
+
+The sequence diagram above shows the interactions of different classes when adding an income to the list.
+
+1. After receiving the `AddCommand` object from `Parser`, `MMM` calls the `AddCommand.executeCommand()` method.
+2. `AddCommand.addIncome()` method is invoked as the `/i` flag is present. It parses through the user's input to obtain
+`AMOUNT` and `CATEGORY` fields. It also runs tests on these fields to ensure the inputs are valid.
+3. An `Income` object is instantiated using the aforementioned fields and is added into the `IncomeList`.
+4. Control is returned to `MMM`.
+
+
+
+#### AddCommand Design Considerations
+Aspect: How to ask user for the fields of input.
+* Alternative 1 (current choice): User is asked to put in all fields at once, separated using flags.
+ * Pros: Faster input, user can enter an expenditure using a single input.
+ * Cons: User must be able to remember all the flags and its sequence.
+
+* Alternative 2: User is asked iteratively to put in all fields, prompted by a message after each input.
+ * Pros: Beginner friendly, easily understandable, no need to remember flags.
+ * Cons: Slower, implementation when user is familiar with the application.
+
+
+
+### CalculateInputCommand feature
+The source code can be found in [`CalculateInputCommand.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/command/CalculateInputCommand.java)
+and [`Calculations.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/helper/Calculations.java)
+
+MindMyMoney allows users to view their finances in a more meaningful manner by displaying the total expenditure and breakdown of expenses in a
+bar chart format.
+
+The CalculateCommand can take in 3 different `[DATE]` fields:
+- `calculate /epm [DD/MM/YYYY]` allows user to calculate total expenditure of the specific date.
+- `calculate /epm [MM/YYYY]` allows user to calculate total expenditure of the specific month.
+- `calculate /epm [YYYY]` allows user to calculate total expenditure of the specific year.
+
+
+
+
+
Fig 11 - Calculate Input Command Sequence Diagram
+
+The sequence diagram above shows the interactions of different classes when calculating the expenditure.
+
+1. After receiving the `CalculateInputCommand` object from `Parser`, `MMM` calls the `CalculateInputCommand.executeCommand()` method.
+2. `GeneralFunctions.parseInput()` method is invoked to obtain the flag and date of the input.
+3. If `/epm` flag is present. It calls `Calculations.calculateExpenditure()` method to obtain the total expenditure of the date specified.
+4. During the execution of `Calculations.calculateExpenditure()`, the `GeneralFunctions.findItemInList()` is invoked to
+find the items that contain the specified date.
+5. Afterwards, `Calculations.displayCalculationBreakdown()` is invoked to show the breakdown of expenses in a bar chart format.
+6. If `/epm` flag is not present, MindMyMoneyException is thrown.
+
+
+
+#### CalculateInputCommand Design Considerations
+Aspect: How to allow users to have a better understanding of their own expenses.
+* User is required to input either the date, month or year in order to calculate their expenses.
+ * Pros: User can have a better understanding of their expenditure breakdowns by the specified time they want to look for.
+ * Cons: User is required to fill in a date, and the date must be found in the list of expenditures.
+
+* Use of bar chart to represent breakdown of expenses in the CalculateInputCommand.
+ * Pros: Users can view their overall expenses in a bar chart format, which is easier to view at one glance.
+ * Cons: Some users may not prefer to visualise their data in a bar chart format.
+
+
+
+### List Command
+The source code can be found in [`ListCommand.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/command/ListCommand.java)
+
+The List Command feature allows users to view their current expenditures, credit cards and incomes, using their
+respective flags:
+- List expenditure `/e`.
+- List credit card `/cc`.
+- List income `/i`.
+
+
+
Fig 12 - List Command Sequence Diagram
+
+The sequence diagram above shows the interactions when a `ListCommand` is executed.
+1. After receiving the `ListCommand` object from `Parser`, `MMM` calls the `ListCommand.executeCommand()` method.
+2. If the expenses flag `/e` is present, it calls the `printExpenditureList()` method.
+3. Else if the credit card flag `/cc` is present, it calls the `printCreditCardList()` method.
+4. Else if the income flag `/i` is present, it calls the `printIncomeList()` method.
+5. Else, it throws an error, which is then handled by printing an error message to the user.
+
+
+
+#### List Expenditure `/e`
+Allows the user to view their list of current expenditures. The list is printed through the `ListCommand.printExpenditureList()`
+method, invoked when using the `/e` flag.
+
+
+
Fig 13 - List Expenditure Sequence Diagram
+
+The sequence diagram above shows the interactions when listing expenditures.
+1. After receiving the `ListCommand` object from `Parser`, `MMM` calls the `ListCommand.executeCommand()` method.
+2. `ListCommand.printExpenditureList()`method is invoked as the `/e` flag is present.
+3. If the optional parameter `{DATE}` is not present, `ListCommand.listString()` method is invoked. This loops through
+`expenditureList` and concatenates each expenditure entry into a String `listInString`.
+4. Else if `{DATE}` is present, `ListCommand.listStringWithDate()` method is invoked. This loops through `expenditureList`
+but only concatenates expenditure entries corresponding to the provided `{DATE}` into `listInString`.
+5. The `listInString` is returned which is then printed out.
+6. Control is returned to `MMM`.
+
+
+
+#### List Credit Card `/cc`
+Allows the user to view their list of current credit cards. The list is printed through the `ListCommand.printCreditCardList()`
+method, invoked when using the `/cc` flag.
+
+
+
Fig 14 - List Credit Card Sequence Diagram
+
+The sequence diagram above shows the interactions when listing credit cards.
+1. After receiving the `ListCommand` object from `Parser`, `MMM` calls the `ListCommand.executeCommand()` method.
+2. `ListCommand.printCreditCardList()`method is invoked as the `/e` flag is present.
+3. `ListCommand.creditCardListToString()` method is then invoked, which loops through the `creditCardList` and
+ concatenates each credit card into a String `listInString`.
+4. The `listInString` is returned which is then printed out.
+5. Control is returned to `MMM`.
+
+
+
+#### List Income `/i`
+Allows the user to view their list of current incomes. The list is printed through the `ListCommand.printIncomeList()`
+method, invoked when using the `/i` flag.
+
+
+
Fig 15 - List Income Sequence Diagram
+
+The sequence diagram above shows the interactions when listing incomes.
+1. After receiving the `ListCommand` object from `Parser`, `MMM` calls the `ListCommand.executeCommand()` method.
+2. `ListCommand.printIncomeList()`method is invoked as the `/i` flag is present.
+3. `ListCommand.incomeListToString()` method is then invoked, which loops through the `incomeList` and
+ concatenates each income entry into a String `listInString`.
+4. The `listInString` is returned which is then printed out.
+5. Control is returned to `MMM`.
+
+
+
+#### List Command design considerations
+Aspect: To ease testing of `ListCommand` using JUnit.
+* Alternative 1 (current choice): Abstract the conversion of `Expenditure`, `CreditCard` and `Income` to `String` in a
+separate `ListCommand.listToString()` method.
+ * Pros: Easily tested using JUnit by checking the String that the `ListCommand.listToString()` method returns.
+ * Cons: Added layer of abstraction that may be deemed redundant.
+
+* Alternative 2: Print directly in the `ListCommand.executeCommand()` method.
+ * Pros: Easily implemented with lesser lines of code.
+ * Cons: JUnit testing would require I/O redirection prior to checking the output matches expectations.
+
+
+
+
+### Delete Command
+The source code can be found in [`DeleteCommand.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/command/DeleteCommand.java)
+
+The List Command feature allows users to delete an entry in their current `Expenditure`, `Credit Card` or `Income` list, using their
+respective flags and followed by the index of the entry to be deleted:
+- Delete an expenditure `/e [INDEX]`.
+- Delete a credit card `/cc [INDEX]`.
+- Delete an income `/i [INDEX]`.
+
+
+
Fig 16 - Delete Command Sequence Diagram
+
+The sequence diagram above shows the interactions when a `DeleteCommand` is executed.
+1. After receiving the `DeleteCommand` object from `Parser`, `MMM` calls the `DeleteCommand.executeCommand()` method.
+2. If the expenses flag `/e` is present, it calls the `deleteExpenditure()` method.
+3. Else if the credit card flag `/cc` is present, it calls the `deleteCreditCard()` method.
+4. Else if the income flag `/i` is present, it calls the `deleteIncome()` method.
+5. Else, it throws an error, which is then handled by printing an error message to the user.
+
+
+
+#### Delete Expenditure `/e`
+Deletes an `Expenditure` specified by the user using the `Expenditure`'s index. The `Expenditure` is deleted through the `DeleteCommand.deleteExpenditure()`
+method, invoked when using the `/e` flag.
+
+
+
Fig 17 - Delete Expenditure Sequence Diagram
+
+The sequence diagram above shows the interactions when deleting an expenditure.
+1. After receiving the `DeleteCommand` object from `Parser`, `MMM` calls the `DeleteCommand.executeCommand()` method.
+2. `DeleteCommand.deleteExpenditure()`method is invoked as the `/e` flag is present.
+3. `expenditureList.get()` method is then invoked, which retrieves the `Expenditure` to be deleted.
+4. `Expenditure.getPaymentMethod()` is then used to check if the payment method was in `CASH`.
+5. For Credit Card payment methods, the amount of expenditure is deducted from `CreditCard.totalExpenditure`.
+6. Details of the deleted `Expenditure` is then printed out.
+7. Control is returned to `MMM`.
+
+
+
+#### Delete Credit Card `/cc`
+Deletes a `Credit Card` specified by the user using the `Credit Card`'s index. The `Credit Card` is deleted through the `DeleteCommand.deleteCreditCard()`
+method, invoked when using the `/cc` flag.
+
+
+
Fig 18 - Delete Credit Card Sequence Diagram
+
+The sequence diagram above shows the interactions when deleting a `Credit Card`.
+1. After receiving the `DeleteCommand` object from `Parser`, `MMM` calls the `DeleteCommand.executeCommand()` method.

+3. `creditCardList.delete()` method is then invoked, which removes the `Credit Card` specified by the user.
+4. Details of the deleted `Credit Card` is then printed out.
+5. Control is returned to `MMM`.
+
+
+
+
+#### Delete Income `/i`
+Deletes an `Income` specified by the user using the `Income`'s index. The `Income` is deleted through the `DeleteCommand.deleteIncome()`
+method, invoked when using the `/i` flag.
+

+Aspect: To print deleted object from User's list.
+* Alternative 1 (current choice): Prints details of deleted `Expenditure`, `Credit Card`, or `Income`.
+ * Pros: Users can easily verify that they have correctly deleted the object as intended.
+ * Cons: Printing extraneous lines onto the Command-Line may affect user-experience and find the output overwhelming.
+
+* Alternative 2: Quietly delete the specified `Expenditure`, `Credit Card`, or `Income`.
+ * Pros: Easily implemented.
+ * Cons: Users are unable to verify that the correct object was deleted.
+
+
+
+### Update Command
+The source code can be found in [`UpdateCommand.java`](https://github.com/AY2122S2-CS2113T-T10-4/tp/blob/master/src/main/java/seedu/mindmymoney/command/UpdateCommand.java)
+
+The Add Command feature allows users to update an `Expenditure`, `Credit Card`, or `Income` using a single command.
+This provides speed and ease of use by only requiring a single line of input, when making amendments to an entry in their list.
+- Update an expenditure `/e`.
+- Update a credit card `/cc`.
+- Update an income `/i`.
+
+
+
Fig 20 - Update Command Sequence Diagram
+
+The sequence diagram above shows the interactions when an `UpdateCommand` is executed.
+1. After receiving the `UpdateCommand` object from `Parser`, `MMM` calls the `UpdateCommand.executeCommand()` method.
+2. If the expenses flag `/e` is present, it calls the `updateExpenditure()` method.
+3. Else if the credit card flag `/cc` is present, it calls the `updateCreditCard()` method.
+4. Else if the income flag `/i` is present, it calls the `updateIncome()` method.
+5. Else, it throws an error, which is then handled by printing an error message to the user.
+
+
+
+
+#### Update Expenditure `/e`
+Updates an `Expenditure` specified by the user using the `Expenditure`'s index. The `Expenditure` is updated through the `UpdateCommand.updateExpenditure()`
+method, invoked when using the `/e` flag.
+
+
+
Fig 21 - Update Expenditure Sequence Diagram
+
+The sequence diagram above shows the interactions when updating an `Expenditure`.
+1. During the execution, `UpdateCommand.updateExpenditure()` will parse through user input to obtain the `PAYMENT_METHOD`, `CATEGORY`, `DESCRIPTION`, `AMOUNT` and `TIME` fields.
+2. Once all the fields are obtained, `UpdateCommand.updateExpenditure()` will run tests for its respective fields.
+3. The `UpdateCommand.updateExpenditure()` object formats the `CATEGORY` and `AMOUNT` fields, and the `PAYMENT_METHOD` if it is in `CASH`.
+4. `UpdateCommand.updateExpenditure()` checks if the updated `Expenditure` is identical to the old `Expenditure` it is replacing, and throws an error if it is.
+5. If the old `Expenditure`'s `PAYMENT_METHOD` or new `Expenditure`'s `PAYMENT_METHOD` is not in `CASH`, `UpdateCommand.updateExpenditure()` invokes `UpdateCommand.updatePaymentMethod()` to update the corresponding `creditCard.totalExpenditure`.
+6. The `UpdateCommand.updateExpenditure()` object instantiates a new `Expenditure` object with the 5 fields and sets it into the `ExpenditureList`.
+7. Details of the updated `Expenditure` is printed out.
+8. Control is returned to `MMM`.
+
+
+
+#### Update Credit Card `/cc`
+Updates a `Credit Card` specified by the user using the `Credit Card`'s index. The `Credit Card` is updated through the `UpdateCommand.updateCreditCard()`
+method, invoked when using the `/cc` flag.
+
+
+
Fig 22 - Update Credit Card Sequence Diagram
+
+The sequence diagram above shows the interactions when updating a `Credit Card`.
+1. During the execution, `UpdateCommand.updateCreditCard()` will parse through user input to obtain the `CREDIT_CARD_NAME`, `CATEGORY`, `CASH_BACK` and `CARD_LIMIT` fields.
+2. Once all the fields are obtained, `UpdateCommand.updateCreditCard()` will run checks for its respective fields.
+3. The `UpdateCommand.updateCreditCard()` object instantiates a new `Credit Card` object with the aforementioned 3 fields and sets them into the `CreditCardList`, at the specified index.
+5. Details of the updated `Credit Card` is printed out.
+6. Control is returned to `MMM`.
+
+
+
+#### Update Income `/i`
+Updates an `Income` specified by the user using the `Income`'s index. The `Income` is updated through the `UpdateCommand.updateIncome()`
+method, invoked when using the `/i` flag.
+
+
+
Fig 23 - Update Income Sequence Diagram
+
+The sequence diagram above shows the interactions when updating an `Income`.
+1. After receiving the AddCommand object from Parser, MMM calls the `UpdateCommand.executeCommand()` method.
+2. `UpdateCommand.updateIncome()` method is invoked as the `/i` flag is present. It parses through the user’s input to obtain `AMOUNT` and `CATEGORY` fields. It also runs tests on these fields to ensure the inputs are valid.
+3. An `Income` object is instantiated using the aforementioned fields and is added into the `IncomeList`.
+4. Details of the updated `Income` is then printed out.
+5. Control is returned to `MMM`.
+
+
+
+#### Update Command design considerations
+Aspect: To allow updating of a similar object from User's list.
+* Alternative 1 (current choice): Throws an exception and warns the user that the updated `Expenditure`, `Credit Card`, or `Income` is similar to the object they are replacing.
+ * Pros: Users can easily verify that they have made a change in the updated object.
+ * Cons: Implementing this requires extraneous checks and increased coupling.
+
+* Alternative 2: Do not warn the user that the old object being replaced is similar to the new object.
+ * Pros: Easily implemented.
+ * Cons: Users may not be aware that the new object has no difference from the old object.
+
+
+
+### Storage
+
+Loads the user's saved information upon startup, and saves the information after every successful
+command execution.
+
+
+
+#### Loading
+
+Loads the user's saved information upon startup.
+
+
+
+Fig 24 - Loading Sequence Diagram
+
+The sequence diagram above shows the interactions when loading user data.
+
+1. On startup, `MMM` creates a `Storage` object that loads and saves data to `data.txt`. The `Storage` object
+creates the file if it does not exist.
+2. `MMM` then calls `Storage.load()`, which initializes a `Scanner` that reads the data file.
+3. `Storage` invokes `User.deserializeFrom()`, which reads a serialized User over the `Scanner`.
+4. `User` calls `ExpenditureList.deserializeFrom()`, which returns an `ExpenditureList` read from the `Scanner`.
+5. `User` then does the same for `CreditCardList.deserializeFrom()` and `IncomeList.deserializeFrom()`, which
+return a `CreditCardList` and `IncomeList`, respectively.
+
+
+
+
+Fig 25 - ExpenditureList Deserialization Sequence Diagram
+
+The above sequence diagram shows the interactions when a list of
+`MMMSerializable`s is being deserialized. Although the given diagram shows the interaction for an
+`ExpenditureList`, the interactions for `CreditCardList` and `IncomeList` are similar.
+
+1. `ExpenditureList` calls `SerializerFunctions.convertInputToList()`, which accepts a function
+that deserializes a line of input. Here, `Expenditure.deserialize()` is passed to `convertInputToList()`.
+2. For each line in the input which corresponds to an `Expenditure`, `SerializerFunctions`
+invokes `Expenditure.deserialize()` on this line, which returns an `Expenditure`. This is repeated until
+the designated terminator is read from the `Scanner`.
+3. `Expenditure` invokes `PropertyList.deserialize()` to convert the input line into a set of key-value pairs.
+Then, it makes a series of `PropertyList.getValue()` calls to obtain the values of each individual property.
+4. Once all attributes have been processed, `Expenditure.deserialize()` returns an `Expenditure`.
+5. These expenditures are aggregated into an `ExpenditureList`, which is returned
+to the `deserializeFrom()` call.
+
+#### Saving
+
+Saves user information after every successful
+command execution.
+
+
+
+
+Fig 26 - Saving Sequence Diagram
+
+The sequence diagram above shows the interactions when saving user data.
+
+1. After every command, `MMM` invokes `Storage.save()`.
+2. `Storage` invokes `User.serialize()`.
+3. `User` calls `ExpenditureList.serialize()`, which returns a `String`, representing the serialized
+`ExpenditureList`.
+4. `User` then does the same for `CreditCardList.deserializeFrom()` and `IncomeList.deserializeFrom()`, which
+ return `String`s representing a serialized `CreditCardList` and `IncomeList`, respectively
+5. `User` compiles all these into one `String`, and returns this to `Storage`.
+6. `Storage` writes the returned serialized `User` into the data file.
+
+
+
+
+Fig 27 - ExpenditureList Serialization Sequence Diagram
+
+The above sequence diagram shows the interactions when a list of
+`MMMSerializable` is being serialized. Although the given diagram shows the interaction for an
+`ExpenditureList`, the interactions for `CreditCardList` and `IncomeList` are similar.
+
+1. `ExpenditureList` calls `SerializerFunctions.addListToStringBuilder()`, passing in an `ArrayList` of
+`Expenditure`s.
+2. For each entry in the list, `SerializerFunctions`
+ invokes `Expenditure.propetyList()` on this line, which returns an `Expenditure`. This is repeated until
+ the designated terminator is read from the `Scanner`.
+3. `Expenditure` creates a `PropertyList` to stores its properties into.
+ Then, it makes a series of `PropertyList.setValue()` calls to save each of its attributes.
+4. Once all attributes have been processed, `PropertyList.serialize()` is called, and
+this serialized `PropertyList` is returned by `Expenditure.serialize()`.
+5. These serialized expenditures are aggregated into an `String`, which is returned
+ to the `deserializeFrom()` call.
+
+#### Storage Design Considerations
+
+Aspect: When to save user data.
+* Alternative 1 (current choice): After every command.
+ * Pros: User state is still saved when program exits in ways other than a `ByeCommand`.
+ * Cons: Saving after every command may degrade performance.
+* Alternative 2: At program exit (i.e. execution of `ByeCommand`).
+ * Pros: Less overhead per command, due to not having to save.
+ * Cons: User state is not saved when program exits otherwise (e.g. due to a crash).
+
+Aspect: What format to use in saving user data.
+* Alternative 1 (current choice): Custom key-value pair format.
+ * Pros: Easy to read and modify by hand.
+ * Cons: More involved implementation.
+* Alternative 2: Java's default `java.io.Serializable` interface.
+ * Pros: Is simple to implement.
+ * Cons: Is non-human-readable, which violates the requirements of this project.
+* Alternative 3: JSON.
+ * Pros: Easy-to-read, widely established standard.
+ * Cons: Requires external libraries.
+* Alternative 4: Incremental list of changes to user data.
+ * Pros: Improved performance, due to having to save less data after every command.
+ * Cons: More difficult to modify by hand.

+# MindMyMoney
-{Give product intro here}
+MindMyMoney (M3) was proposed for users with multiple payment methods who wish to track their expenditures. Conducting
+anecdotal interviews, we realized users face difficulty tracking their expenditures across different payment platforms
+on vastly different items. MindMyMoney was then conceptualized on the basis of tracking user’s expenditures.
+
+The technical goal for the MindMyMoney (M3) is to develop an app for managing your expenditures, optimized for use via
+a Command Line Interface (CLI). MindMyMoney (M3) aims to be a one-stop shop for you to consolidate your expenditure across multiple
+platforms, set budget goals and track your spending.
+
+
+# Quick Start
+
+1. Ensure that you have Java 11 or above installed.
+2. Down the latest version of `MindMyMoney` from [here](https://github.com/AY2122S2-CS2113T-T10-4/tp/releases).
+
+If the setup is correct, you should see the following in your terminal:

+
+
+## Save the Data
+
+Your MindMyMoney data is saved in the hard disk automatically after any command that changes the data. There is no need
+for you to save manually. You can view the saved contents of MindMyMoney by reading the `data.txt` file in your current
+directory.
+
+> **💡 Note:**
+>- If you wish to back up your MindMyMoney data, you can copy the `data.txt` file into the folder you want to save it in.
+>- To load the backup data into MindMyMoney, copy `data.txt` from the backup folder into the folder containing MindMyMoney, replacing the existing copy of `data.txt`.
+
+### Editing the Save File
+If you are experienced in using MindMyMoney, you may wish to directly edit the `data.txt` file. Below is a short
+description of its format.
+
+> **⚠️Warning⚠️**
+>- Be careful when modifying `data.txt` to follow the correct format, since doing so can corrupt the data in MindMyMoney.
+ > When in doubt, keep a backup, as stated above. If you are less experienced, you may use the `update` and `add`
+ > commands to edit the data.
+
+
+`data.txt` must contain the following six lines, in this order:
+
+```
+# BEGIN EXPENDITURES
+# END EXPENDITURES
+# BEGIN CREDIT CARDS
+# END CREDIT CARDS
+# BEGIN INCOME SOURCES
+# END INCOME SOURCES
+```
+
+Each expenditure, credit card, and income is stored in one line between their respective `BEGIN`/`END` lines. No line
+should be left blank.
+
+Each piece of data is stored as a series of `key : value` pairs, separated by spaces. Both `key` and `value`
+are enclosed in quotes. A `\"` in a key or value represents a quotation mark, while a `\\` represents a backslash.
+
+The following are the keys required for each type of data:
+
+- Expenditures contain `amount`, `description`, `paymentMethod`, `time`, and `category` keys.
+- Credit cards contain `totalExpenditure`, `monthlyCardLimit`, `nameOfCard`, and `cashback` keys.
+- Incomes contain `amount` and `category` fields.
+
+Their meanings are the same as in the `add` commands. The `totalExpenditure` key of a credit card contains the total
+amount spent using that credit card.
+
+If a key is missing, MindMyMoney will consider the save file invalid.
+
+Here is an example of a valid save file:
+
+```
+# BEGIN EXPENDITURES
+ "amount": "3.0" "description": "Commute" "paymentMethod": "Cash" "time": "08/03/2022" "category": "Transport"
+ "amount": "1.0" "description": "Mala" "paymentMethod": "DBS" "time": "30/03/2022" "category": "Food"
+ "amount": "1.0" "description": "Chicken rice" "paymentMethod": "DBS" "time": "30/03/2022" "category": "Food"
+ "amount": "1.0" "description": "Katsudon" "paymentMethod": "Cash" "time": "07/03/2022" "category": "Food"
+# END EXPENDITURES
+# BEGIN CREDIT CARDS
+ "totalExpenditure": "2.0" "monthlyCardLimit": "10000.0" "nameOfCard": "DBS" "cashback": "1.0"
+ "totalExpenditure": "0.0" "monthlyCardLimit": "20000.0" "nameOfCard": "OCBC" "cashback": "4.0"
+# END CREDIT CARDS
+# BEGIN INCOME SOURCES
+ "amount": "200" "category": "Allowance"
+ "amount": "500" "category": "Investment"
+# END INCOME SOURCES
+```
+

## FAQ
-**Q**: How do I transfer my data to another computer?
+**Q**: Why is my data not saved when I run MindMyMoney in different folders?
+
+**A**: MindMyMoney saves data in the current directory. To ensure all the data is saved properly, run MindMyMoney only
+in the _home folder_. If you wish to run MindMyMoney in different folders and still contain your data, copy
+the `data.txt` file found in the current directory into a new folder where you want to run MindMyMoney in.

+## Overview
+
+`MindMyMoney` (M3) is a desktop app for managing your personal finances, optimized for use via a Command Line
+Interface (CLI). You can use it to track your expenditures across multiple payment methods, calculate monthly
+expenditure, and set financial goals.
+
+
+## Contribution Summary
+
+### Code Contribution
+
+Code Contribution can be
+viewed [here](https://nus-cs2113-ay2122s2.github.io/tp-dashboard/?search=SeanHoWB&breakdown=true).
+
+Enhancements implemented:
+
+1. Set up the initial structure to build our code base upon.

+
+5. Added `CreditCard` class.
+ - Being part of the value proposition of `MindMyMoney`, it allows users to track their multiple forms of payment.
+
+6. Added `GeneralFunction` class
+ - Allows the team to call frequently used functions in `MindMyMoney` from just one class, increases SLAP.
+ - Implemented `findItemsInList` function that aided the search for expenditure by date and by category in
+ `calculateExpenditurePerMonth`.
+ - Implemented `parseInputWithCommandFlag` to parse user input containing flags. This was used throughout the code
+ across many commands.
+ - Implemented `capitalise`, `formatFloat` functions, to format user input.
+
+7. Added JUnit tests
+ - Added JUnit tests to `AddCommand`, `ListCommand`, `UpdateCommand`, `CalculateInputCommand`,
